Pull x86 tdx update from Dave Hansen:
 "The original tdx hypercall assembly code took two flags in %RSI to
  tweak its behavior at runtime. PeterZ recently axed one flag in commit
  e80a48bade ("x86/tdx: Remove TDX_HCALL_ISSUE_STI").

  Kill the other flag too and tweak the 'output' mode with an assembly
  macro instead. This results in elimination of one push/pop pair and
  overall easier to read assembly.

   - Do conditional __tdx_hypercall() 'output' processing via an
     assembly macro argument rather than a runtime register"
